TRUSS-PAD.

Specification of Letters Patent.

Patented Sept. 9, 1913.

Application :tiled January 22, 1912. Serial No. 672,706.

T 0 all whom t may concern.'

Be it known that I, FRANK L. MGWETHY, citizen of the United States, residing at Marshall, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Truss- Pads, Vof which the following is a specification.

My invention relates to an improvement in truss pads, and the object is to provide a pad which is adjustable to diHerent positions upon the belt, and which maybe turned at an angle to bring the pressure to bear to better advantage upon the ruptured part.

A further object is in the provision of a resilient covering which may be easily andV readily attached and detached from the base.

My invention still further consists in certain novel features of construction and combinations of parts which will be hereinafter' fully described and pointed out in the claim.

In the accompanying .drawings :-*Figure 1 is a view in side elevation of a section of the truss showing my improved pad applied thereto, Fig. 2 is a sectional view on the line 2-2 of Fig. 1, and Fig. 3 is a transverse sectional view through the resilient member of the pad showing the manner of attaching it to the base.

A, is the base which may be made of elliptical or of any other approved form. The base is made preferably of hard rubber, and has a groove 1 around the edge on the rear face thereof, and a flange 2 projecting from the edge on the front face which forms substantially a cup-shaped opening 3. The cup 3 is adapted to be filled with sponge rubber 4 or other resilient material, and an outer covering 5, preferably of soft rubber, is made to iit over the resilient member 4, and has the inner edges turned in to form a flange 6, which is adapted to t into the groove 1 when the cover has beenforced over the flanges 2 of the base and hold the covering removably upon the pad. A turning-member B is provided on the rear of the base A, and has the inner face cored out as shown in Fig. 2 at 7. The Harige thus formed is cut away at points diametrically opposite as at 8 to permit the belt C to pass therethrough. A plate 9, preferably of aluminum or other non-corrosive metal is received within the cored-out portion of the turning member and against the base A, and

a plate V10 also preferably of aluminum is received against the outer side of the member B. Curved slots 1l, 11, are formed through the member B adjacent to the anged portion, and screws 12, 12, pass through openings formed in the plate 10, hence through the slots 1l, through openings formed in the plate 9, and into the base A. In this way the belt C is frictionally clamped between the turning member B and the `plate 9, and the turning-member B is held between plate 10 and base A; The stay strap 13 is attached to the base A at any convenient place by screws 14, 14, and has its free end connected to the belt in any approved manner.

It has been found that to obtain the best results, a resilient pad must beused, and that a uniform resilience should be maintained thereby to keep the pressure upon the affected part even. It has been customary to use a pneumatic pad, but such a pad is found to have its disadvantages. It is further found that better results are obtained in some cases when the pad is held at an angle to the belt.

With my structure, I have provided a pad having a resilient filling and acover removably held over this filling, whereby the filling may be easily and quickly renewed; and at the same time I have provided a belt-holding means which may be adjusted so that the pad will assume a position at an angle to the elt.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is j A truss-pad comprising a base, a pad received upon the face of said base, a turningmember received upon the rear, said turning member cored out so that the belt has free movement therethrough, and provided with curved slots, a plate received upon the turning-member, and screws passing through the plate and slots for clamping the plate against the turning-1nember and holding the pad in its adjusted position on the belt.

In testimony whereof I afliX my signature, in the presence of two witnesses.
